The Flagship Center Channel

Polk's LSi M 706c is more than capable of handling the heavy lifting required of a center channel speaker in a high-performance home theater system. It delivers the kind of effortlessly wide, deep soundstage and realistic imaging that puts you in the middle of the on-screen action.

Product Documentation

Dynamic Sonic Engine

Made up of a 3-1/4" midrange driver and a 1" ring radiator tweeter in its own acoustically sealed enclosure, this tightly spaced duo acts like a "mini-monitor." The precise alignment of the midrange and tweeter allows them to disperse sound over a wide, uniform area with excellent off-axis response in the critical 200 Hz to 2,000 Hz midrange.

Advanced driver material

The new super cell aerated polypropylene uses larger "puffed cells" to create a cone material that's thicker yet lighter than the original. It's used in both the midrange and woofers, allowing them to move faster and with more efficiency.

PowerPort®

Designed exclusively by Polk, this specially shaped "cone" at the mouth of the bass port directs moving air to eliminate bass-stealing turbulence. No turbulence means no wasted power, which means more efficient bass response.
